What are reasons your car will not stay running?

There are several reasons a car may not stay running, including issues with the fuel system, such as a clogged fuel filter or a failing fuel pump, which can prevent adequate fuel delivery. Electrical problems, such as a weak battery or faulty ignition system, can also cause the engine to stall. Additionally, a malfunctioning sensor, like the mass airflow or crankshaft position sensor, can disrupt engine performance. Lastly, problems with the exhaust system, such as a blocked catalytic converter, can lead to stalling issues.
